摘要: 目的:对健身竞走的生物力学特征进行分析，以证实健身竞走是一项能够综合走与跑步优势的运动项目。方法:运用实验法、数理统计法，对普通人完成健身竞走、普通健身走和跑步的运动学、动力学指标进行统计分析。结果:无论在常速还是快速时,健身竞走与普通健身走在步长、步速、步频等方面有显著性差异；健身竞走更容易达到较高的速度和更大的运动强度，并且各关节的地面反作用力均非常显著小于常速跑步。结论:健身竞走有利于实现高效的健身效果，并且受伤的可能性小于跑步，是一项非常安全的运动项目，应进行广泛的推广。  相似文献   

On the elephant in the room: toward a generative politics of place on race in academic discourse     

Baudelaire Ulysse  Theodorea Regina Berry 《International journal of qualitative studies in education》2016,29(8):989-1001

Abstract

In our conceptual essay, we draw on an exchange between a White scholar and a group of panelists on Critical Race Theory at an international conference. Taking up this exchange as our point of departure, we work in dialectical and multidimensional ways between the essentialized politics of place on race and critical anti-essentializing foundations in recent Critical Race Feminism and Critical White Studies’ literatures. Working the dialectics and multidimensionality of the place that race makes in academic discourse, we recognize and ethically work through the essentialized politics of place in advancing anti-essentializing understandings of race. In articulating these anti-essentializing understandings, our conceptual essay drives at the notion of a generative politics of place on race in academic discourse. A generative politics of place holds essentialized realities and anti-essentializing foundations of race in dialectical and multidimensional tension for teaching, learning, and discussing race in local, national, and international contexts.  相似文献   

#OscarsSoWhite: how Stuart Hall explains why nothing changes in Hollywood and everything is changing     

Isabel Molina-Guzmán 《Critical Studies in Media Communication》2016,33(5):438-454

ABSTRACT

Stuart Hall’s work on culture, representation, ideology and hegemony positions Hollywood as a cultural institution informed by and informative of US social values and norms. Thus contemporary debates over Hollywood's diversity are indicative of broader social conflicts. Empirically the article examines 2014–2015 news coverage of Hollywood to question the Hollywood paradox—the lack of diversity in film/TV production yet TV’s increasing shift towards on-screen diversity. It maps three discursive frames: Hollywood exceptionalism, economic imperatives, and institutionalized racism and sexism. The article concludes by using Hulu’s East Los High to reflect on TV’s digital turn and innovative models in production and representation.  相似文献   

The legend of Texas Western: journalism and the epic sports spectacle that wasn’t     

Phillip Hutchison 《Critical Studies in Media Communication》2016,33(2):154-167

This essay interrogates journalistic accounts of Texas Western College’s 1966 college basketball championship, a game in which an all-Black team defeated an all-White team. The analysis traces the evolving portrayals of the game over 45 years. In 1966 American journalists did not emphasize the racial aspects of the game and it was largely forgotten. Twenty-five years later, however, journalists reconstructed the game as a racialized legend, and this account evolved into an epic American narrative. The author argues that the epic portrayals, although aesthetically appealing, reflect problems with accuracy, appropriation, and commercial exploitation. The latter factor led to the legend’s motion picture adaptation as part of a troublesome “White Savior” cinema genre.  相似文献

Voices of teacher candidates of color on white race evasion: ‘I worried about my safety!’     

Yukari Takimoto Amos 《International journal of qualitative studies in education》2016,29(8):1002-1015

Abstract

This qualitative study investigated the negative impacts minority teacher candidates receive from white teacher candidates in a required multicultural education class. The findings reveal that four teacher candidates of color had difficulty positioning themselves among the overwhelming silencing power of whiteness in the class. The white students were tactful at evading power and race and flattening the existing hierarchical power relations through the discourses of colorblindness and by preying on the minority instructor. Their understanding of diversity was also shallow. On the other hand, the teacher candidates of color were afraid that they might be labeled as the ones who spoke up against the white students and fearful of the possibility of retaliation and ostracism from the white peers. It seems that the teacher education program’s structure allowed the white candidates to impose strong negative peer pressure on the teacher candidates of color.  相似文献   

Legacies in Black and White: The Racial Composition of the Legacy Pool     

Howell  Cameron  Turner  Sarah E. 《Research in higher education》2004,45(4):325-351

Selective universities regularly employ policies that favor children of alumni (known as legacies) in undergraduate admissions. Since alumni from selective colleges and universities historically have been disproportionately white, admissions policies that favor legacies have disproportionately benefited white students. For this reason, legacy policies lead to additional costs in terms of reductions in racial diversity. As larger numbers of minority students graduate from colleges and universities and have children, however, the potential pool of legacy applicants will change markedly in racial composition. This analysis begins with a review of the history and objectives of the preference for children of alumni in undergraduate admissions. We then consider the specific case of the University of Virginia and employ demographic techniques to predict the racial composition of the pool of potential legacy applicants to the university. Significant changes in the racial composition of classes that graduated from the University of Virginia from the late 1960s through the 1970s foreshadow similar changes in the characteristics of alumni children maturing through the next two decades.  相似文献

Students’ reception of peer assessment of group-work contributions: problematics in terms of race and gender emerging from a South African case study     

Gladman Thondhlana 《Assessment & Evaluation in Higher Education》2017,42(7):1118-1131

Participatory assessment is increasingly employed in higher education worldwide as a formative mechanism to support students’ active learning. But do students in an increasingly relationally diverse environment perceive that peer assessment of individuals’ contributions to group-work tasks enhances their learning? Recognising the impact of students’ conceptions on the quality of their learning, this study considers students’ perspectives of peer assessment of group-work contributions at a South African university. Questionnaires elicited students’ perspectives of and general attitudes towards assessment of and by their peers. A growing measure of discontent with the process of assessing peer contributions to group tasks emerged, including actual and perceived racial and gender stereotyping, and related rejection-sensitivity. These initial findings were checked against the students’ experiences in a report-and-respond process that enabled probing discussions of the interpretations. This paper examines and explores the implications of such identifications and receptions for learning engagement and group-work curriculum development in the context of a rapidly transforming higher education sector.  相似文献   

The Perceptions of Administrators Concerning the One Florida Initiative     

Adriel A. Hilton  ;Patricia A.Green-Powell  ;Crystal L. Joseph  ;Linda G. Knight 《美中教育评论》2011,(2):233-238

The purpose of this study was to discover the perceptions of Florida law school administrators on the impact of the OFI （one Florida initiative） and the addition of two MSI （minority serving institution） law schools on diversity in Florida＇s legal profession. This research explored the impact of Governor Bush＇s EO （executive order） on diversity within the SUS （state university system） of Florida law schools. Further, this study examined the impact of the creation of two MSI law schools after implementation of the OFI, as perceived by the administrators. The concept of CRT （critical race theory） provides modern legal debates outlining the usefulness of historical civil rights policies in opinionated climates. This study will examine the role of CRT in relation to affirmative action and desegregation case law. CRT forms the framework for examining the impact of the creation of two MSI law schools in the state of Florida. In conclusion, this study found that minority representation in law schools has improved in Florida as a result of the OFI as well as the addition of two MSI law schools. Black representation, however, continues to lag behind other races, particularly the Hispanic population. This study concluded that the OFI has helped improve minority representation in the legal profession.  相似文献
